P. O. Box 101, New Hill, N. C. 27562 November 30,1983 Mr. James P. O'Reilly NRC-146 United States Nuclear Regulatory Commission Region II 101 Marietta Street, Northwest (Suite 2900)

Atlanta, Georgia 30303

Dear Mr. O'Reilly:

In our August 31,1983 letter to you concerning our February 4,1983 response to RII: GFM 50-400/82-39, we notified you that we would require until December 1,1983 to complete our corrective action and be in full compliance with our commitment. This letter is to notify you that the commitment of replacing unidentifiable bolts on all Seismic Category I pumps (Chempumps) by December 1,1983 has not been completed.

The bolts for the Chempumps were ordered and partially replaced. The manufacturing -

tolerances of the bolts have resulted in some bolts being too long. The bolt lengths specified by the vendor have resulted in some of the bolt lengths being satisfactory for seismic consideration but too short to satisfy good engineering practice for thread engagement. ' Because of difficulty obtaining the bolt length information from the Champump supplier and then purchasing the bolts, the installation started too late to correct these problems prior to December 1,1983.- It is currently projected that all necessary rework will be completed and full compliance achieved by January 31,1984.

Thank you for your consideration in this matter.

Yours very truly, W
